VIATRA/DeveloperMeetingMinutes/Meeting20171214

Topics

  • Current status: Bugzilla Gerrit AERI
  • VIATRA 1.7 released
  • VIATRA 1.7.1 seems necessary
  • VIATRA 2.0 status
    • Query runtime uses unchecked exceptions
    • Query explorer removed
    • First milestone build
    • Open questions:
      • Language design: multiple languages vs. pluggable scope dialects
        • Pluggable superlanguage version is much more flexible; would offer many benefits:
          • “Match this pattern over this EMF model, plus this DOORS/etc model, plus this traceability table between them” → easy with hybrid scopes
          • “Template patterns”, restrict certain patterns (both in the incremental and the stateless case) to a few user-supplied starting points (objects or identifiers) at runtime → this can be a use case for a user-supplied (unary) table
        • Pluggable superlanguage may take more initial effort
          • Runtime-level plus language-level composition
          • Solve editor content assist etc. issues…
          • import <<IVQLImportable on classpath>> <<details>>
          • Example importables: epackage, java, user-table etc. ← list should be extensible; also probably deprecate / remove the default case
          • “Details” could be Java package name, EPackage nsURI, user table name/class etc.
          • Give +1000% time budget to Zoltán :)
        • Timeframe? Is it meaningful to release 2.0 with language issues postponed?
    • Feature plans: https://docs.google.com/document/d/125Le7ejjXtLf1Xcz2Opra7Afs6_mm9-ciNXRGDJmmts/edit?usp=sharing
